Abstract
BACKGROUND: Annual influenza vaccination is recommended for all persons aged ≥6 months. The objective of this study was to assess trends in racial/ethnic disparities in influenza vaccination coverage among adults in the United States. METHODS: We analyzed data from the 2007-2012 National Health Interview Survey (NHIS) and Behavioral Risk Factor Surveillance System (BRFSS) using Kaplan-Meier survival analysis to assess influenza vaccination coverage by age, presence of medical conditions, and racial/ethnic groups during the 2007-08 through 2011-12 seasons. RESULTS: During the 2011-12 season, influenza vaccination coverage was significantly lower among non-Hispanic blacks and Hispanics compared with non-Hispanic whites among most of the adult subgroups, with smaller disparities observed for adults age 18-49 years compared with other age groups. Vaccination coverage for non-Hispanic white, non-Hispanic black, and Hispanic adults increased significantly from the 2007-08 through the 2011-12 season for most of the adult subgroups based on the NHIS (test for trend, P < .05). Coverage gaps between racial/ethnic minorities and non-Hispanic whites persisted at similar levels from the 2007-08 through the 2011-12 seasons, with similar results from the NHIS and BRFSS. CONCLUSIONS: Influenza vaccination coverage among most racial/ethnic groups increased from the 2007-08 through the 2011-12 seasons, but substantial racial and ethnic disparities remained in most age groups. Targeted efforts are needed to improve coverage and reduce these disparities. Published by Mosby, Inc.
